Drive Belt Inspection and Replacement
WARNING:
All inspection and replacement are to be performed with
ENGINE NOT RUNNING.
Water pump and generator drive belt (G16 and H25 engines)
Inspection
1) Disconnect negative cable at battery.
2) Inspect belt for cracks, cuts, deformation, wear and cleanliness.
If any defect exists, replace.
Check belt for tension.
Water pump and generator belt tension
ªaº: 6 ± 8 mm (0.24 ± 0.32 in.) deflection for G16, 9 ± 11 mm
(0.35 ± 0.43 in.) deflection for H25 under 100 N, 10 kg or
22 lb pressure
NOTE:
When replacing belt with a new one, adjust belt tension to
5 ± 6 mm (0.20 ± 0.24 in.) for G16, 7 ± 9 mm (0.28 ± 0.35 in.)
for H25.
3) If belt is too tight or too loose, adjust it to specification by adjust-
ing alternator position.
4) Tighten alternator adjusting bolt and pivot bolts.
5) Connect negative cable to battery.
Replacement
Replace belt. Refer to Section 6B for replacement procedure of

0B-6 MAINTENANCE AND LUBRICATION
Water pump, generator, power steering and / or A / C
compressor (if equipped) drive belt (J20 engine)
Inspection
1) Disconnect negative cable at battery.
2) Inspect belt for cracks, cuts, deformation, wear and cleanliness.
If any of above conditions are found, replace.
Also, check belt for tension.
Tension indicator ªBº should be the right of indicator ªAº as
shown in figure. If indicator ªBº is found to the left of indicator ªAº,
replace generator belt.
Replacement
Replace belt referring to Section 6H for replacement procedure of
generator drive belt.
Engine cooling fan drive belt (J20 engine)
Inspection
1) Disconnect negative cable at battery.
2) Inspect belt for cracks, cuts, deformation, wear and cleanliness.
If any defect exists, replace. Check belt for tension.
Cooling fan belt tension
ªaº: 5 ± 7 mm (0.20 ± 0.27 in.) deflection under 100 N, 10 kg
or 22 lb pressure.
NOTE:
When replacing belt with a new one, adjust belt deflection
to 4 ± 5 mm (0.16 ± 0.19 in.).
3) If the belt is too tight or too loose, adjust it to specification by ad-
justing cooling fan pulley position.
4) Tighten adjusting bolt and pivot bolt.
5) Connect negative cable at battery.

AIR CONDITIONING (OPTIONAL) 1B-9
ABNORMAL NOISE FROM CRANKSHAFT PULLEY
ConditionPossible CauseCorrection

A large rattling noise is heard at
idle or sudden acceleration.
Loosen pulley mounting bolt.

Worn or broken bearings.
Retighten bolt.

Replace bearings.
ABNORMAL NOISE FROM TENSION PULLEY
ConditionPossible CauseCorrection

Clattering noise is heard from
pulley.

Pulley cranks upon contact.
Worn or damaged bearings.

Cracked or loose bracket.
Replace bearings.

Replace or retighten bracket.
ABNORMAL NOISE FROM EVAPORATOR
ConditionPossible CauseCorrection

Whistling sound is heard from
evaporator.
Depending on the combination of
the interior / exterior
temperatures, engine rpm and
refrigerant pressure, the
refrigerant flowing out of the
expansion valve may, under
certain conditions, make a
whistling sound.
At times, slightly decreasing
refrigerant volume may stop this
noise.

Inspect expansion valve and
replace if faulty.
ABNORMAL NOISE FROM BLOWER MOTOR
ConditionPossible CauseCorrection

Blower motor emits a chirping
sound in proportion to its speed of
rotation.

Fluttering noise or large droning
noise is heard from blower motor.
Worn or damaged motor brushes
or commutator.

Leaves or other debris
introduced from fresh air inlet to
blower motor.
Repair or replace blower motor.

Remove debris and make sure
that the screen at fresh air inlet is
intact.
